(Washington, DC)  --  The U.S. Supreme Court will review a controversial EPA air pollution rule.  The question involves whether the EPA exceeded its authority in approving strict regulations on coal-fired power plants.  Proponents call the cross-state regulation a critical tool in curbing air pollution.  Opponents say it is an unnecessarily burdensome regulation which will significantly boost electricity costs.   

The U.S. Supreme Court will review presidential recess appointments.  The case involves appointments President Obama made to the National Labor Relations Board when Congress was out of session.  Such appointments otherwise require Senate confirmation.  In taking the President to court, Republicans argued that Congress was not formally in recess, even though nearly all members were out of town.  In agreeing to consider the case, the high court jumps into a major constitutional test of executive power.
